using pyo 0.6.4 on OSX 10.8.3 with python 2.7.2

example from docs VoiceManager (see below) gives error and quits:

Segmentation fault: 11

------------
from pyo import *
s = Server().boot()
s.start()
env = CosTable([(0,0),(100,1),(500,.5),(8192,0)])
delta = RandDur(min=.05, max=.1)
vm = VoiceManager(Change(delta))
sel = Select(vm, value=[0,1,2,3])
pit = TrigChoice(sel, choice=[midiToHz(x) for x in [60,63,67,70,72]])
amp = TrigEnv(sel, table=env, dur=.5, mul=.25)
synth1 = SineLoop(pit, feedback=.07, mul=amp).out()
vm.setTriggers(amp["trig"])
s.gui(locals())
------------

What steps will reproduce the problem?
1. build with --use-jack on Ubuntu Lucid GNU/Linux
2. try the package from https://launchpad.net/~sat-metalab/+archive/metalab
3. launch a pyo.Server(audio="jack") and boot() it.

It should use Jack and just work. Instead, it prints "Pyo built without Jack 
support".

This is pyo 0.4.1 on Ubuntu Lucid GNU/Linux.

What steps will reproduce the problem?

Try to create a CurveTable with a index bigger than the size

e.g.

tab=CurveTable([(0,0),(2048,.5),(4096,.2),(6144,.5),(8192,0)], 0, 20,1024)

What is the expected output?

Error message should be produced.

 What do you see instead?

Though I tried this on Ubuntu Hardy, with Python 2.5

What version of the product are you using? On what operating system?
   pyo 0.6.2 / Windows 7 / python 2.7

Please provide any additional information below.

   SndTable_loadSound function doesn't close the file descriptor when file is loaded by chunks.

What steps will reproduce the problem?
1. I unpack the source in /usr/src/pyo_version..
2. compile with "python ./setup.py build" and get a error message from linker
3. The behaviour is the same with different pyo versions

I get the error message:
pyo_0.6.2-src/src/objects/chorusmodule.c:507: undefined reference to `roundf'
and many other math functions (powf, sinf etc.) too. The above error message is 
the last one from the list i get.


What version of the product are you using? On what operating system?
I use Mageia 1, 64 bit with python 2.7

I try several options for compiling e.g. --use-double but ever the same errors.

Can anyone help on this issue. Please feel free to ask more, may I can help to 
solve this.

Many thanks in advance.

This problem was solved in PyoObject with self._keep_trace and also in FFT 
object (for real, imag and bin Dummy).

Need to check every other objects with special implementation of __getitem__ 
(Notein, Hilbert, Beat, ...) to be sure they "keep trace" of Dummy objects. 
Otherwise, in some case, obj["str"] can't be used more than one time.

Build with --use-jack.

What steps will reproduce the problem?
1. With ASIO4ALL installed on a Windows machine, using an aggregate device 
(input and output) crashes the server

What is the expected output? What do you see instead?
This should be possible with portaudio, another project (SuperCollider) I am 
involved in uses portaudio on Windows and works well with ASIO4ALL. 

What version of the product are you using? On what operating system?
pyo 0.03, python 2.6.5, Windows 7, ASIO4ALL

Please provide any additional information below.
Here is the relevant code in SuperCollider's portaudio implementation: 
http://supercollider.git.sourceforge.net/git/gitweb.cgi?p=supercollider/supercol
lider;a=blob;f=common/Source/server/SC_CoreAudio.cpp;h=216f5dcc965d5d8e242f6e34c
4c66aeef88630d0;hb=677d75339510046d4e53fb588efa0d2827d8b496#l2227

What steps will reproduce the problem?

1. Put these lines in /usr/lib/python2.6/distutils/distutils.cfg 

   [install]
   prefix=/usr/local

2. Execute python setup.py install, not being root 

What is the expected output? What do you see instead?

  I would expect the installation to put all files under /usr/local, as usually do setup.py driven Python packages.

  But parts of the installed files go under /usr/lib, and should not.

What version of the product are you using? On what operating system?

  A recent pyo obtained through git svn clone.

Please provide any additional information below.

  I adjusted permissions of /usr/local so I do not need to be root for installing any Python (or non-Python) packages.  In my opinion, only exceptional circumstances should force someone to be root while installing, and indeed, root is not needed on the wide average.  pyo forces an exception to this, without any good justification that I could see (which absolutely does not mean there is none! ☺).  If there is justification however, it would be nice if it was clearly documented in the installation procedure.

  P.S. I'm very glad that pyo is usable here for me!  Thanks a lot for having created it.  Thanks also to Olivier for the recent presentation at MontrealPython.

What steps will reproduce the problem?
Try the following code:

from pyo import *
s = Server().boot().start()

table = LinTable([(0,0.),(3,.75),(4,1.)], 4)
# the following has similar behavior, although I think it might be more 
"correct":
#table = LinTable([(0,0.),(3,.75),(4,1.)], 5)

sig = Sig(0)
val = Pointer(table, sig)
sine = Sine(freq=440*(2**val), mul=.5).out()

table.graph()
sig.ctrl()
s.gui()

What is the expected output? What do you see instead?
As the Sig slider is moved from 0. to 1., the output of this LinTable should 
slide between 0. and 1. linearly, as is shown in the graph.  Instead, it 
reaches 1. when the Sig is at .75, sits at 1. from .75 to .99..., then becomes 
0. again when Sig reaches 1.  The sine wave in the example code is just used to 
sonify the output of the Pointer.

What version of the product are you using? On what operating system?
pyo 0.6.6 on OS X 10.8.3

Please provide any additional information below.
I've noticed similar behavior using Lookup.

What steps will reproduce the problem?
1. No input device is available (e.g. with Windows 7 and a soundcard with the 
mic/linein unplugged)
2. Booting the Server crashes python

What is the expected output? What do you see instead?
Possibilities: 
* the input should simply be disabled
* an error message should indicate that the server could not boot
* the Server should automoatically use duplex 0 and boot (at the moment setting 
duplex to 0 does not help, python still crashes)

What version of the product are you using? On what operating system?
pyo 0.03, python 2.6.5, Windows 7

Please provide any additional information below.
The problem is linked to portaudio open stream I think...

0.6.3 ubuntu 10.10

In Ubuntu 9.10, pyo gets installed in /usr/local/lib/python2.6/dist-packages

However, it seems that get_python_lib returns
'/usr/lib/python2.6/dist-packages' which means the pyodemos folder and
pyo.py are copied there instead breaking the installation.

According to this post :
https://lists.ubuntu.com/archives/ubuntu-devel/2009-February/027439.html we
need to use --install-layout=deb extra option, using this, all gets
installed in /usr/lib

What steps will reproduce the problem?
1. Run 01_MusicBox.py on windows 7 machine with no input device.

What is the expected output? What do you see instead?

I would expect an informative error message.
I see a message that python.exe has terminated

What version of the product are you using? On what operating system?

6.1. ON windows 7

Please provide any additional information below.

Problem is solved by setting duplex=0  in the server constructor.

1- Copy to clipboard doesn't work.
2- OnKeyDown() doesn't work. That means we can't delete a point!

Maybe other, needs to be fully tested!

It should rather raise a RuntimeError with a message such as "There is no pyo

Please provide any additional information below.

What steps will reproduce the problem?

2. Open Pyo Examples>FFT>01_fft_filter.py
3. Run the example

What is the expected output? What do you see instead?
In Pyo 0.6.4, a graph was displayed automatically. In Pyo 0.6.5, nothing shows 
up.

What version of the product are you using? On what operating system?
Pyo 0.6.5 on OS X Mountain Lion 10.8.2.

Please provide any additional information below.
I recently updated Pyo. I believe that this was my only environment change 
since the last successful graph display. Other examples seem to display widgets 
properly.

Thanks!

It makes no sound.

It would be nice if objects could print out information about current
properties state instead of printing the name and address of the object.
This can easily be done by defining an __repr__ method in the class and
returning a string : 

def __repr__(self):

        return 'Fade in = {0} seconds, Fade out = {1}
seconds'.format(self._fadein, self._fadeout)

Tested on the Fader object and it works great.

Hi,

Will there be Python 3 support?

Python 3 is now the official Python version (and is well on its way to replace 
Python 2). See: http://www.python.org/

Please add Python 3 support! Thank you.

Best regards,
Alexander Rødseth

It would be nice to use the property() method of the class to make the
syntax more pythonic, example for a Since :

sine = Sine()
sine.freq = 400
sine.phase = 0.5

Nice thing about this is you can use both methods (s.freq = value or
s.setFreq and it will behave the same)

The code for the class would look like this :
{{{
class Sine(PyoObject):
    def __init__(self, freq=1000, phase=0, mul=1, add=0):
        freq, phase, mul, add, lmax = _convertArgsToLists(freq, phase, mul,
add)
        self._base_objs = [Sine_base(_wrap(freq,i), _wrap(phase,i),
_wrap(mul,i), _wrap(add,i)) for i in range(lmax)]

    def setFreq(self, x):
        x, lmax = _convertArgsToLists(x)
        [obj.setFreq(_wrap(x,i)) for i, obj in enumerate(self._base_objs)]

    def setPhase(self, x):
        x, lmax = _convertArgsToLists(x)
        [obj.setPhase(_wrap(x,i)) for i, obj in enumerate(self._base_objs)]

    @property 
    def freq(self):
        # return the freq value here

    @freq.setter
    def freq(self, x):
        self.setFreq(x)

}}}

It would seem More elegant to me to store the osc 
addresses in OscReceive as a dictionary instead of a 
list :

    a = OscReceive(port=10001, address=['/pitch', 
'/amp'])
    b = Sine(a[0], 0, a[1]).out()

would become

    a = OscReceive(port=10001, address=['/pitch', 
'/amp'])
    b = Sine(a['/pitch'], 0, a['/amp']).out()

Seems easier to remember that the list index.

What steps will reproduce the problem?
1. start e-pyo
2. select an example

This is Pyo from the SVN on Ubuntu Lucid GNU/Linux.

What steps will reproduce the problem?

from pyo import *
s = Server().boot()
x = 3.4
print "OK here"
f = Biquadx(x)
print " I don't get printed"
s.gui(locals())


What is the expected output? What do you see instead?

I expect to see an error message telling me that the argument x is the wrong 
type. It exits silently


What version of the product are you using? On what operating system?

Sometimes it crashes when reading more than one sound, I think they don't have 
enough time to do multiple hard disk access at the same time...   

Hello,

I am keen to try out the new FFT capabilities but all FFT-based example files 
fail to open with this error:

This is a small issue, but the example code for PVAddSynth has the following 
line, raises a TypeError:

pva = PVAnal(a, size=1024, overlaps=4, pitch=2)

I believe the argument pitch should be changed to wintype?

Loving the 0.6.8 update!

What steps will reproduce the problem?
I'll give several walkarounds I tried, non worked and all ends in 

  JACK error: zombified - calling shutdown handler

  import pyo64
  s= pyo64.Server(audio='jack').boot().start()
  import cv # <-- crashes here

If you do "import cv" above, then it crashes later

  import pyo64
  import cv 
  s= pyo64.Server(audio='jack').boot().start()
  cap= cv.CaptureFromCAM(0) # <-- crashes here

and the same if you do the cap above

  import pyo64
  import cv 
  cap= cv.CaptureFromCAM(0) 
  s= pyo64.Server(audio='jack').boot().start()
  image= cv.QueryFrame(cap) # <-- crashes here

WIth fluidsynth is similar, but there is a walkaround
  import pyo64
  s= pyo64.Server(audio='jack').boot().start()
  import fluidsynth # <-- crashes here

But if you do the "import fluidsynth" above, it all works fine


What version of the product are you using? On what operating system?

I'm using pyo 0.6.0 compiled with --use-double and --use-jack in and 64 bits 
architecture on Ubuntu 10.10


Sorry about the other issue, I pressed enter and it was submitted. I don't know 
how to delete it.

It would be a nice feature to be able to scale the OSC values received from 
OscReceive.  With devices 
like the iPhone and Lemur it is often more complicated to change what it sends 
than to change it 
directly in pyo.  It could work in a similar way as the Max scale object.

Pyo crashes when using a firewire card with coreaudio. It works fine with 
portaudio.

What steps will reproduce the problem?
1. See attached c.py

What is the expected output? What do you see instead?
1.I expect the count to increment with the first trigger
2.I don't expect to see -1


What version of the product are you using? On what operating system?
Latest svn.

Please provide any additional information below.
I have attached my fix for this. Look for PJL comments

What steps will reproduce the problem?
1. python2
2. from pyo import *
3. example(Harmonizer)

What is the expected output? What do you see instead?

Instead of any sounds I get:
  File "/tmp/tmpP1crQz", line 13
    """
      ^
SyntaxError: invalid syntax


What version of the product are you using? On what operating system?
python2-pyo 0.6.1
python2 2.7.3
64-bit Arch Linux

Please provide any additional information below.

What steps will reproduce the problem?

1. Install as admin
2. Try running E-Pyo as usual user.

What is the expected output? What do you see instead?

E-Pyo.exe can not find .epyo

Please provide any additional information below.

Copying .epyo as admin fixes the problem but it would be nice if the install 
worked without having to get admin to do this!

What steps will reproduce the problem?

 See attached file.


What is the expected output? What do you see instead?

  I expect doit to get called.   It does not.

What version of the product are you using? On what operating system?

  0.6.1  (from the trunk)

Please provide any additional information below.

I want to use pyo as an interactive effects-building block. Think of a 
distributed daw.

I'd use a fifo file for sound input and communicate with pyo via stdin and an 
interactive python session. pyo should then only output to stdout, not play on 
my sound card.

How would you approach this?

I was thinking about

play mysound.wav > soundin
python play_snd.py

And play_snd.py would start a server, read from soundin, apply effects etc., 
and output to stdout.

The only way to use stdout I've found is a JACK-utility, however I'm not sure 
how well that scales.

Thanks for this project, it looks really promising!

To reproduce, enter the following at a python prompt:

>>> from pyo import *
>>> s = Server().boot()
>>> a = Sin(1)

The result is that the python interpreter quits with the message, "TypeError: 
"input" argument must be a PyoObject." Instead, it should throw an exception, 
but the interpreter should continue running. This is caused by calling 
Py_Exit(1); as the standard way of dealing with error conditions, instead of 
using the exception routines, such as PyErr_SetString().

This is catastrophic for using pyo in interactive contexts, as any such minor 
mistake will quit the interpreter and force you to start again.

I am sure there are other instances of this mistake - pressing the Quit button 
in the GUI also quits the interpreter if there is one! So if you want to launch 
the GUI to view some waveforms, you must set up another thread in the 
interpreter because otherwise once you start it, you can never get the 
interpreter back!

It works if copied and execute as a python script but not as an example...

The test directory should contain unit tests. (if any)

In Change example, the printed value is not the current one, but the last one.

I tried to install pyo under a virtualenv on Ubuntu and it did not work.

To reproduce:
1. Install all dependencies using apt-get
2. Make a virtualenv and activate it
3. Run 'python setup.py install'
4. Try to import pyo. The traceback is attached.

I am using the last svn version (as of today).

Run any pyo script with Jack support.

We often see "JACK error: zombified - calling shutdown handler".

Sometimes it's OK, sometimes it's not.

It's on Ubuntu Lucid, Natty, etc.
